Docker 容器 RestartCount 未递增
Docker container RestartCount not incrementing
测试
def test_can_pop_new_container(self):
config = {
'ip': '10.49.0.2',
'subnet': '10.49.0.0/16',
'gateway': '10.49.0.202',
'vlan': 102,
'hostname': 'test-container',
}
container = container_services.pop_new_container(config, self.docker_api)
inspection = self.docker_api.inspect_container(container.get('Id'))
print('before', inspection.get('RestartCount'), inspection.get('StartedAt'))
container_services.restart(container, self.docker_api)
new_inspection = self.docker_api.inspect_container(container.get('Id'))
print('after', new_inspection.get('RestartCount'), new_inspection.get('StartedAt'))
代码
def restart(container, docker_client):
return docker_client.restart(container.get('Id'))
输出
通过测试我得到
before 0 None
after 0 None
来自 docker ps
确认容器已重新启动。

问题
那为什么RestartCount
还在0
?我是否使用了错误的字段?
正如评论中已经指出的那样,RestartCount
字段用于 Restart Policies 的上下文中,以在出现故障时跟踪重新启动尝试。
如果用户启动重启,它不会增加。
你可以看看docker events to keep track on normal container restarts. This is also available for dockerpy.
